Product Overview
This high-quality Original Clutch Variator Plate Ramp is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2018-2020).
The variator plate ramp, also known as the roller guide or ramp plate, sits within the variator assembly and provides the angled surfaces along which the CVT rollers travel as centrifugal force acts on them. The ramp profile precisely controls the rate at which the rollers move outward, directly governing the smoothness and progressiveness of ratio changes across the rev range. Worn or grooved ramp surfaces alter the roller travel path, causing vibration, hesitation, uneven acceleration and premature roller wear. This original replacement is manufactured to original factory specifications, restoring correct roller guidance and smooth, progressive CVT operation.

Complete Part Guide
The Clutch Variator Plate Ramp (22131-KWN-900) for the Honda PCX125 2018-2020 is the critical guide component that controls the movement of the roller weights within the front variator. Over time, the internal channels can become "notched" or worn, preventing the rollers from sliding linearly and causing the transmission to "hang" at specific RPMs rather than shifting smoothly. This original Honda replacement features the factory-calibrated ramp angles and surface hardness required to restore crisp throttle response and optimal fuel economy for North London commutes. In stock at Part Hive's London warehouse, order before the 1 PM cutoff for same-day UK dispatch.
We frequently see 2018-2020 models where the transmission feels "notchy" or sluggish, often caused by worn guides on the variator ramp plate. On the Honda PCX-125, the 22131-KWN-900 plate works in tandem with the plastic slide pieces. If the metal "ears" on this plate become sharp or burred, they will shred new sliders within miles. Furthermore, if the plate is warped from overheating, it will cause the roller weights to rattle, leading to a loud "clattering" sound at idle. Fitting this original Honda PCX-125 part ensures a quiet, balanced drivetrain, and in our experience, using the original plate avoids the premature wear on the variator boss and crank splines often caused by out-of-balance low-grade aftermarket plates.
